Issues for 1.8.0

• New features
  • WebAssembly Port!
    • This is still experimental: Be careful to use this.
    • Flappy example
    • Chipmunk physics engine example
      • Much faster than GopherJS version!
  • Polygon support (experimental)
    • DrawTriangles function
    • Polygons example
  • Multi monitors support
    • The window starts in the current monitor.
    • The fullscreen is done in the current monitor.
  • Faster Ogg/Vorbis decoder on browsers
    • The decoder is now Wasm and works in a Web Worker.
  • TPS (Tick per second)
    • Tick is a unit to represent logical time. TPS means how many times the game is updated in a second.
  • Automatic mipmap image creation
    • More beautiful linear filtering
• New APIs
  • Polygons
    • type DrawTrianglesOptions: represents options to render triangles on an image.
    • type Vertex: represents a vertex passed to DrawTriangles.
    • func (i *Image) DrawTriangles(vertices []Vertex, indices []uint16, img *Image, options *DrawTrianglesOptions): draws a triangle with the specified vertices and their indices.
  • TPS
    • func CurrentTPS() float64: eturns the current TPS (ticks per second), that represents how many update function is called in a second.
    • func MaxTPS() int: returns the current maximum TPS.
    • func SetMaxTPS(tps int): sets the maximum TPS (ticks per second), that represents how many updating function is called per second.
  • Vsync
    • func IsVsyncEnabled() bool: returns a boolean value indicating whether the game uses the display's vsync.
    • func SetVsyncEnabled(enabled bool): sets a boolean value indicating whether the game uses the display's vsync.
  • Package audio
    • func (c *Context) IsReady() bool: returns a boolean value indicating whether the audio is ready or not.
    • func NewInfiniteLoopWithIntro(src ReadSeekCloser, introLength int64, loopLength int64) *InfiniteLoop: creates a new infinite loop stream with an intro part.
  • Package ebitenutil
    • func DebugPrintAt(image *ebiten.Image, str string, x, y int): draws the string str on the image at (x, y) position.
  • func IsDrawingSkipped: returns true if rendering result is not adopted. Renamed from IsRunningSlowly.
  • func ScreenSizeInFullscreen() (int, int): returns the size in device-independent pixels when the game is fullscreen.. Renamed from MonitorSize.
  • func Wheel() (xoff, yoff float64): returns the x and y offset of the mouse wheel or touchpad scroll.
  • func (g *GeoM) Skew(skewX, skewY float64): skews the matrix by (skewX, skewY).
• Deprecated APIs
  • func IsRunningSlowly() bool: Use IsDrawingSkipped instead.
  • func MonitorSize() (int, int): Use ScreenSizeInFullscreen instead.
• Bug fix
  • Multi monitors issues
  • macOS 10.14 Mojave issues
